Problem:

After changing the issue type of the issue from Epic to Story by clicking on the issue type icon, the epic color field changes to the issue color field and remains with the summary tab. 

In this case, the issue color field is not added to the screen, but the epic color field automatically changes to issue color and it is a default field like summary which cannot be removed now. 

Suggested Solution

Allow the ability to remove the issue color field OR remove the field issue color after changing the issue type if it is not added to the screen.

Why This Is Important

In general, the standard issues don't contain the field issue color but when the issue type is changed from Epic the field is visible which can create confusion for users.
